Let's solve the arithmetic expressions one by one:
1. (-3)-(-12)+15:
To simplify this expression, we need to remember the rules of subtraction and addition with negative numbers. When subtracting a negative number, it is equivalent to adding its positive counterpart. Thus, (-3) - (-12) can be rewritten as (-3) + 12.
(-3) + 12 + 15 = 9 + 15 = 24
2. (-16)-(-15)-14:
Similar to the previous expression, we rewrite (-16) - (-15) as (-16) + 15.
(-16) + 15 - 14 = -1 - 14 = -15
3. 14-(-23)-(-15):
Following the same principle as before, we rewrite 14 - (-23) as 14 + 23, and (-15) as 15.

THANKS FOR MARKING AS BRAINLIEST
Step-by-step explanation:
Let's solve the arithmetic expressions one by one:
1. (-3)-(-12)+15:
To simplify this expression, we need to remember the rules of subtraction and addition with negative numbers. When subtracting a negative number, it is equivalent to adding its positive counterpart. Thus, (-3) - (-12) can be rewritten as (-3) + 12.
(-3) + 12 + 15 = 9 + 15 = 24
2. (-16)-(-15)-14:
Similar to the previous expression, we rewrite (-16) - (-15) as (-16) + 15.
(-16) + 15 - 14 = -1 - 14 = -15
3. 14-(-23)-(-15):
Following the same principle as before, we rewrite 14 - (-23) as 14 + 23, and (-15) as 15.
14 + 23 - 15 = 37 - 15 = 22
4. -46 -(-45) + 16:
Again, we rewrite -(-45) as +45.
-46 + 45 + 16 = -1 + 16 = 15
Therefore, the results are:
1. (-3)-(-12)+15 = 24
2. (-16)-(-15)-14 = -15
3. 14-(-23)-(-15) = 22
4. -46 -(-45)+16 = 15
